    • Abstract
  • In bathymetric survey,the recorded seabed is distorted due to the beam-width of the echo sounder.It is important to eliminate or degrade the effect caused by the beam width of echo sounders and reflect the true seabed.The biggest problem is calculating the seabed slope angle of the unknown seabed.So,a new method for calculating the seabed slope angle called the differential method is put forward.The test results show that the new method is useful and effective.
